Biological Markers of Disease in the Prediction of Preterm Delivery, Preeclampsia and Intra-Uterine Growth Retardation: A Longtitudinal Study

Official Title ICMJE

Biological Markers of Disease in the Prediction of Preterm Delivery, Preeclampsia and Intra-Uterine Growth Restriction: A Longitudinal Study

Brief Summary

Preterm delivery, preeclampsia and intrauterine growth restriction are leading causes of perinatal morbidity and mortality. Efforts to treat these syndromes have not been effective, most likely becuase these obstetric complications are the clinical expression of adaptive mechanisms of host defense developed in response to pathologic insults. Since the ultimate pathologic basis of disease is unclear, therapy for these syndromes has been largely directed at symptoms, which appear late in the development of the disease. The main purpose of this study is to perform an early and comprehensive exploration of maternal and fetal factors that predict the subsequent develpment of these obstetrice complications, so that early medical interventions may be tested in patients at high and low risk for adverse perinatal outcome.

Detailed Description

Preterm delivery, preeclampsia and intrauterine growth restriction are leading causes of perinatal morbidity and mortality. Efforts to treat these syndromes have not been effective, most likely because these obstetric complications are the clinical expression of adaptive mechanisms of host defense developed in response to pathologic insults. Since the ultimate pathologic basis of disease is unclear, therapy for these syndromes has been largely directed at symptoms, which appear late in the development of the disease. The main purpose of this study is to perform an early and comprehensive exploration of maternal and fetal factors that predict the subsequent development of these obstetric complications, so that early medical interventions may be tested in patients at high and low risk for adverse perinatal outcome.

Low risk group: normal pregnancy with no risk factors for preterm delivery, pregnancy-induced hypertension or intrauterine growth retardation (control population, selected between 6 and 22 weeks at the prenatal care clinic). The rationale to include this group is that 50-70% of preterm deliveries occur in patients without risk factors for preterm birth.

Consent to participate in the study.

Patient should be able to attend each Perinatal Research Center for prenatal care and participation in this study.

EXCLUSION CRITERIA:

Preterm labor, preterm PROM, preeclampsia or impaired fetal growth at the time of recruitment.

Any maternal or fetal condition that requires termination of pregnancy.
